Reading your message makes me wonder whether you are familiar with the reason why memory barriers exist, something the Wikipedia authors of the page about double-checked locking clearly are aware of ? Reading the paper "x86-TSO: a rigorous and usable programmer's model for x86 multiprocessors" might help. It does not only discuss memory models in general but also explains why effects like inter-processor store reordering are observed with certain processor families but not with x86 CPUs.
